“…The median follow-up period was 18 months (range = 12 to 120 months). The client population varied greatly across the cohorts, including people with co-occurring disorders (Bush et al, 2009;Xie et al, 2010;McHugo et al, 2012), people early in the course of illness (Drake et al, 2013), people with severe mental illness over 45 years of age (Twamley et al, 2008), and people with significant illness-related impairments in functioning (i.e., severe mental illness) (Mueser et al, 1997;Lam and Rosenheck, 2000;Torrey et al, 2000;Bond et al, 2001;Twamley et al, 2008;Burns et al, 2009;Xie et al, 2010;Kilian et al, 2012;Kukla et al, 2012;McHugo et al, 2012). Participants were recruited from community mental health centers in the US (Mueser et al, 1997;Torrey et al, 2000;Bond et al, 2001;Twamley et al, 2008;Bush et al, 2009;Xie et al, 2010;Kukla et al, 2012;McHugo et al, 2012) and abroad (Burns et al, 2009;Kilian et al, 2012), emergency departments (Drake et al, 2013), as well as emergency shelters, outdoors, and public or abandoned buildings (Lam and Rosenheck, 2000).…”
